Abstract

PURPOSE:To enable designing property to be improved, and cut the diamond in the direction to be previously displayed and comparatively simply by applying fine cut decoration due to a diamond bite, to the finger ring of comparatively rough rugged design due to molding (casting) or the like. CONSTITUTION:In the case where rugged decorative design is applied on the surface of the accessory of a precious metal finger ring, a precious metal pendant, a precious metal bracelet, or the like, for the finger ring for example, on the base metal of the finger ring 4, a mound section 5 and a groove section 6 are formed, and along the groove section 6, the cutting edge 2a of a diamond bite 2 is moved, and the oblique surface of the groove section 5 is chipped with the cutting edge 2a of the diamond bite 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for decorating jewelry such as rings of precious metals such as gold, pendants of precious metals and bracelets of precious metals.

[0002]

2. Description of the Related Art In the case of jewelry rings such as precious metal rings, precious metal pendants and precious metal bracelets, for example, decorative rings, which are called design rings, have recently become popular with precious metal rings such as gold and platinum. It is designed to have various irregular shapes around the ring and also to be embedded with jewels.

On the other hand, as a method for producing a precious metal ring, there is also a method in which a seamless tube is sliced to obtain a ring metal, and in the case of the design ring having the uneven shape as described above, a die (prototype) is used to cast a precious metal casting. Molding as (cast)
I often do it. According to such mold forming, since the design can be realized by the mold, the rings having the same shape can be easily made.

[0004]

However, in the design ring having the uneven shape formed by the die molding (casting), there is a limit to the fineness, and when a more delicate pattern is applied,
Cutting techniques are used. For cutting,
There are methods such as engraving using Tsuchi and chisel and diamond cutting using a diamond cutting tool that is a rotary blade.

Of these methods, the diamond cutting method can save time and labor compared to using chisel. However, conventionally, only a flat surface is used to perform diamond cutting. For example, as shown in FIG. 7, a diamond bit 2 is formed on the surface of the ring 1 whose outer peripheral surface is flat. Thus, the cut groove 3 is formed, and the decorative design is formed by various combinations of the cut groove 3.
The flatness of the surface to be diamond-cut is because it is difficult if the planned drawing of the cut groove 3 is not flat.

The object of the present invention is to solve the above-mentioned disadvantages of the conventional example, and to design a design ring having a relatively rough uneven shape by molding (casting) or the like and further applying a fine cut decoration with a diamond bite to design. The object of the present invention is to provide a method of decorating accessories such as rings which can improve the property and can be performed relatively easily because the direction of the diamond cutting is shown in advance.

[0007]

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a ring of precious metal such as a precious metal ring, precious metal pendant, precious metal bracelet, etc. Form the peaks and valleys, move the diamond bite blade along the valleys, and cut the inclined surface of the valleys with the diamond bite blade to create a decorative design with unevenness on the surface of the precious metal ring. In the case of applying, the ingot of the ring forms peaks and troughs, the blade of the diamond bite is moved along the troughs, and the inclined surface of the troughs is cut with the blade of the diamond bite. To do.

[0008]

According to the present invention, the design of a relatively rough uneven shape by molding (casting) or the like is added to the accessory such as a ring, which is further subjected to a fine cut decoration by a diamond cut, so that the uneven design is obtained. And a diamond cut design is mixed to obtain a novel design ring.

Moreover, this diamond cutting is performed on the inclined surface of the valley portion, and the blade of the diamond cutting tool enters the concave portion which is the valley portion, and it is possible to cut well, and the line at the bottom of the valley portion is used as a guide. By moving the blade, you can get an accurate design cut without relying on intuition.

[0010]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 to 4 show a method of decorating jewelry according to the present invention 1
FIG. 5 is a vertical sectional front view showing each step showing an embodiment, and FIG. 5 is a front view showing an example of a ring manufactured by the method of the present invention.

Reference numeral 4 in the drawing denotes a ring made of a precious metal such as gold. The ring 4 is formed by molding (casting) or the like.
The ingot of the ring has a mountain portion 5 and a valley portion 6 to give a relatively rough design. In addition, the design of this uneven shape may be the entire circumference of the ring 4,
There may be only a part of the front side or other parts, and there is no particular limitation.

A diamond bite 2 is attached to such a ring 4.
Diamond cutting is performed by using the diamond cutting tool 2 along the valley 6 as shown in FIG.
By moving a, the inclined surface 6a of the valley 6 is cut by the blade 2a of the diamond cutting tool 2.

As shown in the figure, if two peaks 5 are arranged side by side, the inclined surface 6a of the central valley 6 is cut, and then, as shown in FIG.
The inclined surface 6a of the valley portion 6 at the left end is cut as shown in FIG. 4, and the inclined surface 6a of the valley portion 6 at the right end is cut as shown in FIG. In the case where there are a plurality of such valleys 6, which valley 6 is to be cut may be freely selected.

In any case, the diamond bite 2
The blade 2a is made to enter the concave portion which is the valley portion 6, and the blade 2a is moved by using the bottom line of the valley portion 6 as a guide. By doing this, even if the valleys 6 are continuous in a curved line, by following the bottom line of the valleys 6 with eyes, the blade 2a can be accurately moved without relying on intuition.

As shown in FIG. 5, the produced ring 4 has a diamond cutting surface 7 formed by the diamond bite 2 on the inclined surface 6a of the valley portion 6 in FIG. 1, and the diamond cutting surface 7 is a blade. Since 2a is moved little by little, a beautiful finished surface is obtained after cutting as shown in the figure.

FIG. 6 shows an application example of the present invention. By embedding a jewel such as a diamond 8 in the ring 4 and cutting the periphery thereof as described above, the jewel can be enhanced by the diamond cut surface 7. ..

Although the above embodiment has been described with respect to the case of a ring, the same method can be applied to other accessories such as a precious metal pendant and a precious metal bracelet.

[0018]

As described above, the method of decorating an accessory according to the present invention is such that a design ring having a relatively rough unevenness formed by molding (casting) or the like is further subjected to finely cut decoration with a diamond bite. Therefore, the design can be improved, and the diamond cutting can be performed relatively easily because the direction is previously indicated.
